Many years ago while reading through the Manual of The Mother Church by Mary Baker Eddy, I came across the following By-Law:
“Christian Science Nurse. SECT. 31. A member of The Mother Church who represents himself or herself as a Christian Science nurse shall be one who has a demonstrable knowledge of Christian Science practice, who thoroughly understands the practical wisdom necessary in a sick room, and who can take proper care of the sick.
“The cards of such persons may be inserted in The Christian Science Journal under rules established by the publishers” (p. 49).
